Seems a lot of people have been asking lately, because they look so similar, so here are the differences:

They share about 90% of the same parts, but there are a few changes that make the 635 unique to the Ballistic line of helicopters.

The tail assembly IS a shortened version of the 700 as far as the boom, supports, torque tube and control rod. The canopy is the same as the 700, and the gears are the same.

The 635 offers a new and improved main frame for optimized 635 performance over using the standard Ballistic main frame with a shorter boom.

The auto unit has been optimized for the 635 as well, reducing weight and cost.

The bottom line is: If you own any of our high quality competition helis, you own about 90% of any of our other models already should you choose to convert.

Shops take up less space with our complete line than most helicopters use with one model. For example, a shop or customer can easily support 8 different Rave kits on one 8×8 foot wall of parts. Customers can keep spare parts for multiple helis in one stash.
You can’t beat the combination of performance, quality, price and versatility of a Curtis Youngblood product!
